Linux Foundation Announces Intent to Form LF Decentralized Trust

29 juin 2024 à 17:34

This week the Linux Foundation announced a new organization for decentralized systems and technologies, with an aim of "fostering innovation and collaboration" in both their development and deployment. It will build on existing Linux Foundation blockchain and digital identity projects, according to the announcement, while supporting "a rapidly growing decentralized technology landscape." To foster this broader ecosystem, LF Decentralized Trust will encompass the growing portfolio of Hyperledger projects and host new open source software, communities, standards, and specifications that are critical to the macro shift toward decentralized systems of distributed trust.... LF Decentralized Trust's expanded project and member ecosystem will be both essential to emerging tokenized assets classes and networks, as well as to modernizing the core infrastructure for finance, trade, government, healthcare, and more. LF Decentralized Trust will serve as a neutral home for the open development of a broad range of ledger, identity, security, interoperability, scale, implementation, and related technologies... LF Decentralized Trust will also include new directed funding models that will drive strategic investments by members into individual projects and project resources. "With LF Decentralized Trust, we're expanding our commitment to open source innovation by embracing a wider array of decentralized technologies," said Jim Zemlin, Executive Director of the Linux Foundation. "This new, elevated foundation will enable the community to build a more robust ecosystem that drives forward transparency, security, and efficiency in global infrastructure." "After eight years of advancing the development of blockchain, decentralized identity and related technologies via the Hyperledger community, the time has come to broaden our effort and impact," said Daniela Barbosa, General Manager, Blockchain and Identity, the Linux Foundation. "Ledgers and ledger technologies are but one component of the decentralized systems that will underpin a digital-first global economy. LF Decentralized Trust is where we will gather and grow an expanded community and portfolio of technologies to deliver the transparency, reliability, security and efficiency needed to successfully upgrade critical systems around the world." The announcement includes quotes of support from numerous companies including Oracle, Siemens, Visa, Accenture, Citi, and Hitachi. Some highlights: "The formation of the LF Decentralized Trust reflects the growing demand for open source resources that are critical to the management and functionality of decentralized systems." — CEO of Digital Asset "The adoption of decentralized infrastructure is at an inflection point, reflecting the increasing demand from both enterprises and consumers for more secure and transparent digital transactions. As the industry leader for onchain data, blockchain abstraction, and interoperability, we're excited to see the formation of the LF Decentralized Trust and to expand our collaboration with leading financial institutions on advancing tokenized assets and the onchain economy at large." — CMO at Chainlink Labs. "As a founding member of the Hyperledger Foundation, and given our unique position in the financial markets, we recognize the vast potential for open-source innovation and decentralized technologies when it comes to reducing risk, increasing resiliency and improving security. The expansion of Hyperledger Foundation into LF Decentralized Trust represents an exciting opportunity to continue expanding these groundbreaking technologies." — a managing director at DTCC

In November of 2022, "More than 800 people were selected to participate in the Denver Basic Income Project," reports the Colorado Sun, "while they were living on the streets, in shelters, on friends' couches or in vehicles. One group received $1,000 a month, according to the article, while a second group received $6,500 in the first month, and then $500 for the next 11 months. (And a "control" group received $50 a month.) Amazingly, about 45% of participants in all three groups "were living in a house or apartment that they rented or owned by the study's 10-month check-in point, according to the research." The number of nights spent in shelters among participants in the first and second groups decreased by half. And participants in those two groups reported an increase in full-time work, while the control group reported decreased full-time employment. The project also saved tax dollars, according to the report. Researchers tallied an estimated $589,214 in savings on public services, including ambulance rides, visits to hospital emergency departments, jail stays and shelter nights... The study, which began in November 2022 with payments to the first group of participants, has been extended for an additional eight months, until September, and organizers are attempting to raise money to extend it further.

Tom's Hardware reports that Japan's National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) set a 402 terabits per second data transfer record — over commercially available optical fiber cables. The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate. As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent. "This is achievable with currently available technology used by internet service providers..." the article points out. "With 'beyond 5G' potential speeds achievable through commercially available cables, it will likely further a new generation of internet services."

Are 'Immortal Stars' Feasting on Dark Matter in the Milky Way's Core?

"Stars very close to the center of our galaxy could be fueled by dark matter in perpetuity," writes Gizmodo, "according to a team of astronomers who recently studied the distant light sources." The group of stars, known as S-cluster stars, is just three light-years from the center of the Milky Way (for reference, we are about 26,000 light-years from the center of our galaxy, which hosts a supermassive black hole at its core). The stars are surprisingly young for their galactic neighborhood, yet they don't look like stars that simply migrated to this part of the Milky Way after forming in another location... As reported by Space.com, the research team posits that these weird stars may be accreting dark matter, which they then use as fuel to keep burning. Since models estimate there is plenty of dark matter near the galaxy's core, the stars are "forever young," as study lead author Isabelle John, an astrophysicist at the Kavli Institute for Particle Astrophysics and Cosmology told Space.com. Effectively, the stars have a long, long way to go before they start running low on fuel. The team's paper is currently hosted on the preprint server arXiv, meaning it has not yet gone through the process of peer review. Dark matter is only "seen" through its effects on other objects, the article points out — leading to lots of theories as to where it's actually located. "Earlier this year, a different team of researchers proposed that neutron stars — extremely dense stellar remnants — could actually be a source of dark matter. Last July, yet another team suggested that the Webb Telescope had detected stars that were powered by dark matter."
